3.4L Hard Start Question
 
I'm looking at a 1995 Camaro with the 3.4L V6 engine. the car is hard to start if it's been sitting for a few hours or overnight. However, once the car has started and has warmed up, it runs fine.
I'm wondering what the issue might be with the hard starting problem and what I'm looking at for cost to repair the problem. There is no check engine light and the engine runs perfectly smooth once it starts. As I said, once it warms up, the engine starts right up with no problems.
Any info is greatly appreciated as I'm looking at buying this car if the cost isn't too much to fix the hard start problem.

Thanks!

It could be a number of things, from something bad, so something simple and cheap to fix. Going to need more info. Does it turn over slow? Does it sputter when you're trying to start it? Anything coming out the tail pipe? Does it burn oil?

The car doesn't turn over slow at all. The oil is clean and the exhaust is clean as well. Once the car starts, the engine runs great and there is no "hiccups" or sputtering. When the car is put in gear the engine runs fine and doesn't act like it wants to stall either. With the exception of the cold hard start, there doesn't seem to be any issues at all with the car.

a hard start after sitting for a while is usually a sign of check valve issues in the fuel pump, allowing the fuel to drain back to the tank over time. at startup you have to wait for fuel to reach the injectors, sometimes a few seconds. try priming a couple of times, turning the key on for a second or two and back off. if it starts fine then you know what it is.
Mine starts fine, just hard start after hot, trying to figure that out myself!

There's so many variables. Plugs, fuel pump, IAT, crank sensor. Does the RPM needle jump at all at idle?

Wow, it's been over a year. I hope he got it fixed by now.

I had some of the same issues, mine was the fuel pump.
